Class SeamExceptionMapper

java.lang.Object
  org.jboss.seam.rest.exceptions.SeamExceptionMapper

All Implemented Interfaces:

ExceptionMapper<Throwable>

Direct Known Subclasses:

CatchExceptionMapper

@Provider
@ApplicationScoped
public class SeamExceptionMapper
extends Object
implements ExceptionMapper<Throwable>

This ExceptionMapper implementation converts caught exceptions to HTTP responses based on exception mapping rules.

If there is no matching rule for an exception, the exception is rethrown wrapped within UnhandledException. Note that this implementation is replaced by CatchExceptionMapper in environments where Seam Catch is available.
